As we create new units and/or as the game auto-generates units for us, they are added to the bottom of the list. When we go to train new units, they are shown in the same order as on the list in the Unit Design window. It would be really great to be able to select a unit on the list and have up and down arrows to move the unit up or down the list so we can put them in a logical order. For instance, I really like to have my units in order of cheapest to most expensive, or weakest to strongest (not necessarily the same thing) but I imagine someone else might like to group spear units together, sword units together, bow units together, etc. So, no need to add complicated sorted options, just give us up and down arrows and we can sort them ourselves.
